The short version

  • Each has a real cost: Aiven the free plan gives 1 VM with 1 CPU, 1 GB RAM and 1 GB storage, and cannot pick a specific cloud or region; RisingWave anything that does not fit SQL, such as custom windowing, complex event processing or heavy stateful logic, still needs Flink, so RisingWave often adds a system rather than removing one.
  • They diverge on capability: Aiven covers Multi-cloud Support, RisingWave covers SQL materialised views.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aiven

  • The free plan gives 1 VM with 1 CPU, 1 GB RAM and 1 GB storage, and cannot pick a specific cloud or region
  • Free and Developer tiers have no integrations and no connection pooling
  • Connection pooling, database forks and dynamic disk sizing need the Business or Premium plan
  • A 99.99 percent uptime SLA starts at the Startup plan from $75 a month
  • High availability with automatic failover starts at Business from $180 a month

RisingWave

  • Anything that does not fit SQL, such as custom windowing, complex event processing or heavy stateful logic, still needs Flink, so RisingWave often adds a system rather than removing one.
  • The Apache 2.0 community edition excludes premium features behind a licence key, and which capabilities sit on which side of that line moves between releases, so a self-hosted plan can be invalidated by an upgrade.
  • Long-running materialised views accumulate state in object storage, and cost and recovery time grow with retention in ways that are hard to forecast before you are in production.
  • The Postgres compatibility is protocol level; it is not a transactional Postgres and using it as a general purpose database, with point updates or high write concurrency, goes badly.
  • It is a comparatively young venture-funded project competing with Flink, Materialize and warehouse-native streaming, and the ecosystem of connectors, operators and third-party expertise is much thinner.

RisingWave: Is RisingWave open source?

The community edition is Apache 2.0 and self-hostable, but a set of premium features requires a paid licence key.

Aiven: How is Aiven billed and what are the monthly costs for each tier?

Aiven bills services by the hour and invoices monthly, charging only for what you actually run. PostgreSQL pricing starts at 5 dollars per month for Developer, 12 dollars per month for Hobbyist, 75 dollars per month for Startup, 180 dollars per month for Business, and 270 dollars per month for Premium. All paid tiers offer hourly billing options as well.

It starts at 0.227 US dollars per RisingWave Unit hour on the Basic tier, which is capped at 64 cores.

Aiven: What backup retention periods are included at different Aiven tiers?

Backup retention increases with tier level: Startup tier provides 2 days of backup retention, Business tier offers 14 days, and Premium tier includes 30 days. Point-in-time restore is available on all paid tiers.

RisingWave: Does it replace Flink?

For SQL-expressible transformations, often yes. For custom stateful processing and complex event handling, no.

Aiven: Is high availability included in Aiven pricing or charged separately?

High availability, backups, and routine maintenance are all included in the tier costs with no separate charges. The Business tier includes 2 VMs with automatic failover, and Premium includes 3 VMs with a second standby node.

Source
RisingWave: Can I query it like Postgres?

Yes over the Postgres wire protocol, but it is an analytical streaming engine, not a transactional database.

Aiven: Does Aiven offer a trial period to test premium features?

Aiven offers a 30-day free trial to access premium features beyond what the free plan provides.
